This was pulled off a 1987 Porsche 944 engine.  I don't know when the engine last ran - sold as is.  I would assume at the very least the injectors need rebuilding.  This will work on any 2.5 liter 8 valve Porsche 944 from 1985.5 to 1989 including the 944 turbo and 924S.  The injectors are only for an NA 2.5 liter with the 8 valve head.
